Take a Tour

Watershed Signage

Signage installed at Griggs, O'Shaughnessy & Hoover Reservoirs invites park visitors to  take a self-guided tour along the shoreline & learn about the green infrastructure installed there.

Rain gardens, porous pavement & more can improve the quality of storm water entering the reservoirs that supply our drinking water.

Hoover Boardwalk Improvements

The parking area for the popular Hoover Nature Preserve Boardwalk currently consists of gravel with no parking space or traffic markings. Because of the heavy use, there is often rutting, erosion and stormwater runoff into the nearby water. This lot is located on the banks of Hoover Reservoir, which is a drinking water source for over a half million consumers. On an average day, over 100 people visit the boardwalk. This area is often busy during the fishing seasons and year-round for the birding opportunities. Seeing the need for improvements, the Division of Water applied for and successfully obtained a grant from the Ohio EPA's Surface Water Improvement Fund program to make better use of the space, eliminate rutting, improve handicapped parking and better protect water quality. 

Construction for the improvement, at the north end of Hoover in Galena, begins in early May and involves the installation of 3,375 square feet of permeable pavers along with a concrete entrance that will drain to the paver areas at the boardwalk (see map). The project will include permeable pavers within the parking spaces to allow the stormwater to percolate into the ground, which is better for water quality than running off and picking up contaminants before it enters the reservoir. The area outside the pavers will include a vegetated infiltration area. This project will not only demonstrate innovative practices for passively treating and managing stormwater and reducing non-point source pollution, but will also inform visitors about how these systems work through educational signage.

Project construction details:
• Installing silt fencing and other water protection practices
• Clearing and grubbing to prepare site
• Sub-soiling the existing parking area to reduce compaction
• Installing aggregate base
• Installing concrete curbing around parking area
• Installing pervious pavers within the parking spots
• Pouring a concrete entrance and middle section of the parking area
• Pouring a short section of sidewalk from the ADA parking to the boardwalk
• Marking of 20 vehicle spaces, 2 ADA parking spaces and new signage
• Installing interpretive signage about the use of permeable pavement and its benefits
• Reseeding disturbed area
• Installing waterfowl exclusion fences to protect new growth from goose grazing
